Thermal-insulation container and magnetospinograph using same

A thermally insulated container, comprising:

• an inner container;
• and
• an outer container surrounding the inner container via a void, wherein
• each of the inner container and the outer container includes a fiber reinforced plastic prepared by impregnating a base material including fibers with a resin,
• the inner container comprises
• a first cylindrical container and a second cylindrical container each having an internal accommodation space to reserve a refrigerant, and
• a refrigerant inlet tube through which the refrigerant is introduced into the first cylindrical container,
• the accommodation space of the second cylindrical container is in communication with the accommodation space of the first cylindrical container,
• the base material in each of a predetermined area of the second cylindrical container and a predetermined area of the outer container includes a woven fabric and a unidirectional fiber sheet fabricated by aligning multiple fibers to one direction,
• the outer container surrounds the second cylindrical container such that the unidirectional fiber sheet in the predetermined area of the second cylindrical container is opposed to the unidirectional fiber sheet in the predetermined area of the outer container;
• and
• a superconducting quantum interference device for detecting a magnetic field generated from a living body,
• wherein, the superconducting quantum interference device is accommodated in the accommodation space of the second cylindrical container while being immersed in the refrigerant reserved in the accommodation space of the second cylindrical container;
• wherein a measurement surface of the superconducting quantum interference device is opposed to the predetermined area of the outer container and the predetermined area of the second cylindrical container;
• wherein the predetermined area of the outer container is a region to which a load of the living body is applied during detection of the magnetic field.
